Umf...problem with a converter function

[Topper_Harley]

Hey guys, thanks for stopping by.

I'm trying to make a function that recieves an array as an argument. If this array has some empty ("") arguments, the function converts them to the value "N/A" and returns the array. The thing is that although the function seems to work (the print returns the changes correctly) when I execute the sql that has this array as argument it still shows empty fields instead of "N/A" fields....

Am I missing something?

The function is:

//converts $array[i] = "" to $array[i] = "N/A"
function nulear ($array)  {
    foreach($array as $k => $v) {
        if ($v == ""){
            $v = "N/A";
        }
    }
    return $array;
} #end nulear

The rest of the script I'm trying to execute is something like:

echo $array[0] // It shows ""
nulear($array);
echo $array[0] // It still shows "" instead of "N/A"!!!
$sql = "INSERT INTO Table VALUES (null,\"$array[0]\",\"$array[1]\",\"$array[2]\",\"$array[3]\")";
$result = mysql_query ($sql,$link); 

Thanks in advance!

Instead of just doing nulear($array);, you have to assign it, so use $array = nulear($array);

[mrhappiness]

or you do

function nulear(&$array)

pay attention to the &

but what you reall yhave to do is:

$array[$k] = "N/A";

instead of

$v = "N/A";
